본 발명은 차량용 연료 필러(filler)에 관한 것이며, 특히 연표탱크에 급유할 때 증발가스가 대기로 방출되는 것을 억제하는 연료 필러에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle fuel filler and, more particularly, to a fuel filler that suppresses the release of boil-off gas into the atmosphere when refueling a soft tank.
주지하는 바와같이 차량에서 배출되는 가스는 그 배출원에 따라 배기가스, 블로바이가스, 증발가스로 구분되며, 상기한 증발가스의 배출을 억제하는 방식으로 연료탱크내의 증발가스를 크랭크케이스에 저장하거나 활성탄캐니스터에 흡착저장하였다가 연료실에 공급시켜 재연소시키고 있다. 그러나 이들은 연료탱크의 연료 필러를 마개로 막았을 때에는 증발가스가 대기중으로 배출되는 것이 억제되나, 급유를 위하여 연료 필러의 입구를 막은 마개를 열었을 때에는 연료탱크내의 증발 가스가 연료 필러를 통하여 대기로 방출되고 있는 것이다. 즉 종래의 연료 필러는 마개를 열고 급유노즐을 필러본체에 삽입하고 연료를 연료탱크에 급유함과 동시에 연료탱크내에 저장되어 있던 증발가스가 레벨링튜브와 급유노즐지구에 형성된 벤트공을 통하여 대기중으로 방출되는 것이므로 현재와 같은 증발가스 배출억제대책으로서는 앞으로 강화되는 증발가스의 규제추가를 만족하지 못하게 되는 것이다.As is well known, the gas discharged from the vehicle is classified into exhaust gas, blow-by gas, and evaporated gas according to the emission source, and the evaporated gas in the fuel tank is stored in the crankcase or activated carbon in a manner that suppresses the emission of the evaporated gas. It is adsorbed and stored in the canister and supplied to the fuel chamber for reburn. However, when the fuel filler of the fuel tank is plugged, the evaporative gas is prevented from being released into the atmosphere.However, when the plug is opened to block the inlet of the fuel filler for refueling, the vaporized gas in the fuel tank is discharged to the atmosphere through the fuel filler. It is becoming. In other words, the conventional fuel filler opens the cap, inserts the oil supply nozzle into the filler body, feeds the fuel into the fuel tank, and releases the evaporated gas stored in the fuel tank into the atmosphere through the vent hole formed in the leveling tube and the oil supply nozzle zone. As a countermeasure against evaporative gas emissions as of now, it will not satisfy the additional regulation of evaporative gas.
본 발명은 상기한 실정을 감안하여 급유를 위하여 마개를 열고 급유노즐을 필러에 삽입하면 증발가스가 대기로 방출되지 않는 차량용 연료 필러를제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a fuel filler for a vehicle in which evaporation gas is not discharged to the atmosphere when a stopper is opened for oil supply and a fuel supply nozzle is inserted into a filler.
본 발명은 상기한 목적을 달성하기 위하여 필러본체와, 상단이 상기 필러본체의 입구에 고정되고 하단에 급유노즐지지관을 형성하여 실을 설치한 실하우징과, 상기 급유노즐지지관에 고정함과 동시에 필러본체 내벽에 지지되며 급유노즐통과공과 벤트공이 뚫린 도어하우징과, 상기 도어하우징에 힌지결합되어 급유노즐통과공과 벤트공을 폐쇄하는 트랩도어와, 필러본체의 도어하우징 상하와 연료탱크에 연결된 벤트튜브와 레벨링튜브로 구성한 것이다.The present invention is a filler body, and the upper end is fixed to the inlet of the filler body and the bottom of the seal housing to form a lubricating nozzle support pipe at the bottom and the thread is installed, and to the lubricating nozzle support pipe to achieve the above object and At the same time, the door housing is supported on the inner wall of the filler main body, and the door housing through which the lubricating nozzle passage hole and the vent hole are opened, the trap door which is hinged to the door housing to close the lubricating nozzle passage hole and the vent hole, the upper and lower door housings of the filler body, and the vent connected to the fuel tank. It consists of a tube and a leveling tube.
이하 실시예를 도면에 의하여 설명한다.Embodiments will be described below with reference to the drawings.
도면 제1도 및 제2도에서 1은 필러본체이고, 2는 실하우징으로서 상단은 필러본체(1)의 입구에 고정되고, 하단에는 급유노즐지지관(3)을 형성하여 반원형의 홈(4)을 형성한 후 외면주위에 돌기가 형성되고 내부가 중공으로 된 실(5)이 설치되어 있다.In FIGS. 1 and 2, 1 is a pillar body, 2 is a seal housing, and an upper end is fixed to the inlet of the pillar body 1, and an oil supply nozzle support tube 3 is formed at the lower end thereof to form a semicircular groove 4. ), A protrusion is formed around the outer surface, and a seal 5 having a hollow inside is installed.
6은 도어하우징으로서, 급유노즐지지관(3)의 하단에 고정됨과 동시에 필러본체(1)의 내벽에 밀폐시켜 지지되며, 급유노즐지지관(3)과 동일한 급유노즐통과공(7)과 급유노즐통과공(7)의 외측으로 벤트공(8)이 뚫려 있고 급유노즐통과공(7)과 벤트공(8)을 포함하는 외주에 실(9)이 설치되어 있다.6 is a door housing, which is fixed to the lower end of the oil supply nozzle support tube 3 and is sealed and supported on the inner wall of the filler main body 1, and the same oil supply nozzle passing hole 7 and oil supply as the oil supply nozzle support tube 3 are supplied. A vent hole 8 is drilled outside the nozzle passage hole 7, and a seal 9 is provided on an outer circumference including the oil supply nozzle passage hole 7 and the vent hole 8.
10은 트랩도어로서, 상기 도어하우징(6)의 일측에 힌지결합되어 상기 급유노즐지지관(3)과 벤트공(8)을 급유하지 않을 때 즉 마개(16)가 닫쳐있을 때에는 필러본체(1)에 핀(11)으로 지지된 스프링(12)에 의하여 닫쳐져 있도록 되어 있다.10 is a trap door, which is hinged to one side of the door housing 6 so that the filler main body 1 when the lubrication nozzle support pipe 3 and the vent hole 8 are not lubricated, that is, when the stopper 16 is closed. ) Is closed by a spring 12 supported by a pin 11.
12는 벤트튜브로서 도어하우징(6)의 상부 위치의 필러본체(1)와 연료탱크(13)사이에 연결되어 있다.12 is a vent tube, which is connected between the filler body 1 and the fuel tank 13 at the upper position of the door housing 6.
14는 레벨링튜브로서 도어하우징(6)의 하부 위치의 필러본체(1)와 연료탱크(13) 사이에 연결되어 있다.14 is a leveling tube which is connected between the fuel tank 13 and the filler body 1 at the lower position of the door housing 6.
15는 진공밸브로서, 연료탱크(13)에 부압이 작용하면외기가 흡입되어 부압을 해제함과 동시에 급유시에 급유저항도 해제하는 것이다.15 denotes a vacuum valve. When negative pressure is applied to the fuel tank 13, outside air is sucked in to release the negative pressure and at the same time release the oil supply resistance at the time of refueling.
16은 마개로서 이는 통상의 것과 같이 필러본체(1)의 입구를 막으며, 연료탱크에 부압이 작용하면 상기 진공밸브(15)가 열림과 동시에 마개가 열려서 외기가 연료탱크(13)로 흡입되는 구조로 되어 있다.16 is a stopper, which blocks the inlet of the filler main body 1 as usual, and when the negative pressure acts on the fuel tank, the vacuum valve 15 is opened and the stopper is opened so that outside air is sucked into the fuel tank 13. It is structured.
미 설명부호 17은 캐니스터이고, 18은 급유노즐이다.Reference numeral 17 is a canister and 18 is a lubrication nozzle.
이상과 같은 본 발명은 마개(16)가 닫혀있을 때에는 스프링(12)의 탄성에 의하여 트랩도아(10)가 닫혀있으므로 연료탱크(13)내에서 발생되는 증발가스는 캐니스터(17)에 흡착저장되어 있다가 엔진의 가동시에 연소실에 공급되어 재연소되는 것은 종래와 같으며, 연료탱크(13)에 부압이 발생되면 진공밸브(15)와 마개(16)가 열려서 대기가 벤트튜브(12)를 통하여 연료탱크(13)에 공급되는 것이다.In the present invention as described above, since the trap door 10 is closed by the elasticity of the spring 12 when the stopper 16 is closed, the evaporated gas generated in the fuel tank 13 is adsorbed and stored in the canister 17. While the engine is supplied to the combustion chamber and re-burned during operation of the engine, when a negative pressure is generated in the fuel tank 13, the vacuum valve 15 and the stopper 16 are opened, and the atmosphere opens the vent tube 12. It is supplied to the fuel tank 13 through.
그리고 연료탱크(13)에 급유를 하기 위하여 마개(16)를 열고 급유노즐(18)을 급유노즐지지관(3)에 밀어 넣으면 트랩도어(10)가 열림과 동시에 급유노즐(18)의 외주면은 급유노즐지지관(3)에 형성된 홈(4)에 설치한 실(5)에 밀착되고, 진공밸브(15)는 닫혀 있으므로 연료탱크(13)와 대기는 차단상태에 있어 연료탱크(13)내의 증발가스는 레벨링튜브(14)로 이동된 후 벤트공(8)과 벤트튜브(12)를 통하여 다시 연료탱크(13)에 되돌아가서 저장되거나 캐니스터(17)에 흡착저장되는 것이다.In addition, when the stopper 16 is opened and the oil supply nozzle 18 is pushed into the oil supply nozzle support pipe 3 to supply fuel to the fuel tank 13, the trap door 10 opens and the outer peripheral surface of the oil supply nozzle 18 In close contact with the seal 5 provided in the groove 4 formed in the oil supply nozzle support tube 3, and the vacuum valve 15 is closed, the fuel tank 13 and the atmosphere are in a blocked state. After the evaporated gas is moved to the leveling tube 14, the gas is stored back into the fuel tank 13 through the vent hole 8 and the vent tube 12, or is adsorbed and stored in the canister 17.
이상과 같이 본 발명은 급유를 위하여 급유노즐을 필러본체에 밀어 넣었을 때 급유노즐의 외주를 급유노즐지지관에 설치한 실에 의하여 밀폐토록하여 증발가스의 대기방출이 억제되므로서 증발 가스대책에 만전을 기할 수 있을 뿐 아니라, 차량의 전복시에도 연료누츨이 없으며, 마개를 막았을 때에도 실하우징에 진공밸브를 설치하여 연료탱크에 발생하는 부압을 해소할 수 있으며, 트랩도어는 도어하우징에 설치한 실에 의하여 완전히 밀폐되므로 증발가스가 대기로 방출되지 않는다.As described above, in the present invention, when the oil supply nozzle is pushed into the filler body for oil supply, the outer periphery of the oil supply nozzle is sealed by a seal installed in the oil supply nozzle support pipe so that the air emission of the evaporation gas is suppressed, and thus it is perfect for the prevention of the evaporation gas. In addition, there are no fuel leaks when the vehicle is overturned, and even when the plug is closed, a vacuum valve can be installed in the seal housing to relieve the negative pressure generated in the fuel tank, and the trap door is installed in the door housing. Since it is completely sealed by the seal, no evaporating gas is released to the atmosphere.
그리고 급유노즐지지관에 설치한 실은 외면주위에 돌기가 형성되어 있고 내부는 중공으로 되어 있어 밀폐가 양호하고 실의 수명이 긴 효과 등이 있는 것이다.In addition, the thread installed in the oil supply nozzle support tube has protrusions formed on the outer surface and the inside is hollow, so that the sealing is good and the life of the thread is long.
